To, all whom ti in ay concenii Be itknowrt that I, ROLOF J been: BEN, doctor of philosophy, chemical engineer, and resident of Karlsgasse,

Prague-Zizkow, Austria-Hungary, have invented certain new and useful improvements in Apparatus for Carbonizing'Wood, Peat, and the Like, of which'the following a lull, clear, and exact description, reference being bad to the accompanying drawings, ionning 'part of this specification. p

' The object of this'in'vention is to so improve the construction and arrangement of the parts of the apparatus as. to completely-and effectually utilize the products of diiitillation during the process of carbonization of wood,

and the like in kilns.

V 7 -In the accompanying drawings -.-Figure 1represents l vertical section taken on the line QC D of Fig. 2; Fig 2 is a vertical section. taken on the line A B of Fig. 1.

' Reierringto the drawings, 1 designates the carbonizing chambery? thedrying chamber, and 3 the cooling chamber. The carbonizingchamber is providedwith of one wall 5 to the lower end of the opposite wall 8. The bottom is also preferably inclined from its center to the two walls at angles to the walls5 and 6 of the retort. In the upper part of said chamber are two openings]. which serve for introducing the material to be carboniaed, and are provided with. suitable closures, as flat valves 8.

heating means consists of a urnace10 arranged v '9 indicates a pipe adapted to convey the gases conin the products of distillation to a suitable cooling arrangement, not shownthe outside and lower third part of the retort, the Iheat' being communicated to the said re'tdrt by a horiserves toipredry the material to be carbonizeda'ndis.

I z oiitally arranged pipe 11. At the lower extremity of thel retort and at each side of the inclined bottom are pip 'es 12.having pipe 13 common to both, =for use intoceiving and carrying to a suitable collecting-chamber, notyshowm ta r which is an especially valuable product to med-during thecarbonizing of fur wood.

he chamber21ocatedat one side of the retort h ted by a. suitable mixture of burned gas and air admitted from pipe llby the slide door-.14. 4 Separating the carbonizing chamber from thecooling chamber is a slide door 1 5 operated by a chain 16. The I cooling chamber 3 is still furtherout off from the carhonizing chamber by means oi-a door 17. In the cooling'chamber are arranged closed pipes 18 of a great radiation surface, through whichthe permanent gases cir- Jculate .comingjroig I the condenser through pipe. 19. channel -20* are formedin the bottom of said cham er and are coyered by 21 with tracks 22 mount- "es l'lhe; channels are in communication-with and sorvs'to'iurther cool the'ooatenta at 1 Specification of Letters Patent!

the' cooling chamber, the air having free access to the channels.

The operation of my improved apparatus is as ioll'oytsz-{lhe material such as wood, peat, lig'nite, and the like'to be carbonized is-first thoroughly dried in chamb21732. It is then discharged through the openings 7 into the carbonizing chamber l,=where it is carbonized, the tar or like residuum resulting from such process be? ing carried off by pipe 13. v Alter the foregoing process has been completed the slide doors l5 and 17 are opened thereby causing coke or other substance to automatically slide down to the cooling chamber 3, being deposit ed either directly upon the floor of said chamber or upon cooling cars 23. In the former case the 'material iallsdown on iron plates 21, beneath which the cold air is densed gases are admitted from the condenser through 7'0 circulated in channels of brick work 20. The non-conpipe 19 and by passing the pipes 18 are heated to such a degree that they may be easily inflamed on entering the furnace through pipe24. ,In consequence ofthe high preheating of these gases the heat required for the carlbonization is reduced in a manner hitherto unknown. 1; The burnedgases give off the greatest part of their boat to the heating pipes 311 theietort; are then mixed with air introduced; in any suitable way and passedby the slide door 14, to the drying chamber 2.

These gasesaro then drawn off; by means of any mechanical contri vance, preferably an exhaust fan 26, and passed to the open air. Ii-these gases are not to be used for p'redrying the material, slide door 14 is closed and door 25 opened, and in this way are passed through chimney 27 to the open air.

The chimney 27 is provided with a holeor channel 30 Which'isin communication with the open air and may be.closed by a slide door 31-. ,It is obvious thatupon the slide door 31 being opened the air will be drawn in through the hole or channel 30 by exhaust fan 26, then miiicd with the gases of combustion, and finally passed to the drying chamber. lnthis way the gases of combustion may be cooled, if they are hotter than required,

by drying the material' to be treated. If it is desired-to lessen the amount of "labor and avoid the iormation of dust, the burned or decomposed material may be; de;

"posited in suitable iron' ars 23 and'coolddnfi manner as hereinbefore described, thence conveyed to-a store chamber without further manipulation. The b'rickwork channels 20 are open'at both ends in orderto keep air circulating for cooling purposes.
